Good morning, recently I built a stabilizer for the spindle arm of my 1991 SHOPTASK MILL. With X amount of force applied perpendicular to the arm at the Z spindle axis the dial read out was .003". With the stabilizer arm attached to tail stock as shown in the photos and the same X force applied the read out was about 0 to .0005". (See attached photos) don't do much lathe operations with this machine, It works for me!
